Ireland experiences four distinct seasons, though the weather is famously "changeable" and often features "four seasons in one day." Spring (March to May) is a time of renewal, where the landscape turns its most vibrant green, and temperatures range from 8°C to 15°C. It is a relatively dry time of year and perfect for seeing lambs in the fields. Summer (June to August) is the peak tourist season, with the longest daylight hours—the sun often doesn't set until 10:00 PM. Temperatures average between 15°C and 20°C, though rare heatwaves can push it higher. Autumn (September to November) brings stunning orange and gold foliage and the harvest season. Temperatures drop to 10°C to 14°C, and it becomes noticeably windier and wetter. Winter (December to February) is the darkest and wettest season. While extreme cold and snow are rare due to the warming influence of the North Atlantic Drift, temperatures hover around 4°C to 8°C. Rain is frequent, and the days are short, but it is a cozy time for visiting traditional pubs. Regardless of the season, a waterproof jacket is an essential item for any trip to the Emerald Isle.
